Benefits of technology

[0027] An advantage of the present invention is to provide a liquid crystal display panel adapted to minimize movement of a spacer, and a fabricating method thereof.

Problems solved by technology

However, it is difficult to uniformly scatter the plurality of ball spacers because of a limitation in the uniformity of the scattering method.
When the plurality of ball spacers is scattered non-uniformly, the cell gap becomes non-uniform.
This causes the problematic generation of a spot in a screen.
Thus, the usage rate of the material is not good and its fabrication process is complicated.
Thus, the ink-jet spraying device is different from the ball spacer scattering method of the related art which has the limitation in the uniformity thereof.
This causes deterioration in a cell gap uniformity of the LCD panel and deterioration in a contrast ratio.

Embodiment Construction

[0043] Reference will now be made in detail to an embodiment of the present invention, example of which is illustrated in the accompanying drawings.

[0044] With reference to FIGS. 4 to 8, embodiments of the present invention will be explained as follows.

[0045]FIGS. 4 and 5 are diagrams representing a part of an upper plate of a liquid crystal display (LCD) panel according to an embodiment of the present invention.

[0046] Referring to FIGS. 4 and 5, the upper plate of the LCD panel may include a black matrix 42 formed to divide pixel areas on a first substrate 41. The upper plate may also include red, green and blue color filters 48 formed at each of the divided pixel areas. The color filters 48 include holes 47. The holes 47 include a first hole 47a and a second hole 47b that may be divided by a color filter dam 48a for minimizing the movement of a ball spacer 46.

[0047] The first and second holes 47a, 47b and the color filter dam 48a are formed to face a thin film transistor devic...

Abstract

This invention relates to a liquid crystal display panel adapted to minimize movement of a spacer, and a fabricating method thereof. A liquid crystal display panel according to an embodiment of the invention includes a black matrix formed on a first substrate and formed in a boundary between pixel areas for dividing the pixel areas; red, green, and blue color filters formed at the divided pixel areas; at least two holes adjacent to each other on the black matrix; at least one dam dividing the adjacent holes; and a spacer restricted within at least one of the at least two holes.

Description

[0001] This application claims the benefit of Korean Patent Application No. 10-2005-0051654, filed on Jun. 15, 2005, which is hereby incorporated by reference for all purposes as if fully set forth herein. BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] The present invention relates to a liquid crystal display panel and a fabricating method thereof. More particularly, the present invention relates to a liquid. crystal display panel adapted to minimize movement of a spacer, and a fabricating method thereof. [0004] 2. Description of the Related Art [0005] Generally, a liquid crystal display (LCD) device controls the light transmittance of liquid crystal material by using an electric field to thereby display a picture. The LCD device includes an LCD panel where liquid crystal cells are arranged in a matrix. The LCD device also includes a drive circuit used to drive the LCD panel. [0006] The LCD panel includes pixel electrodes and a reference electrode, i.e., a commo...
